On the nonlinear behaviour of bimodular multilayered plates (Q1192802)

Summary: In an earlier study by \textit{G. Porco, G. Spadea} and \textit{R. Zinno} [Atti Accad. Naz. Lincei, VIII. Ser., Rend. Cl. Sci. Fis. Mat. Nat. 83, 159-176 (1989; Zbl 0732.73027)] the nonlinear behaviour of unimodular laminated plates was studied. This paper, following the previous study, concerns a large deflection analysis of moderately thick rectangular plates having arbitrary boundary conditions and finite thickness shear moduli. The plates are manufactured in bimodular materials and constructed in a cross-ply fashion or in a single layer with arbitrary fibre direction angle. Numerical results are obtained by a finite element technique in which are specified five degrees of freedom, three displacements and two bending slopes per node. Furthermore, the effects of plate aspect ratio, bimodularity ratio and fibre orientation are studied; finally, comparisons with some results available in literature are also given.
